All I can say is 'maybe', but more likely 'not'. I just looked at a few policies at insuremytrip.com and found the following in one of the high end policies as being eligible for trip interruption/cancellation reimbursement: "Common Carrier delays resulting from inclement weather, or mechanical breakdown or organized labor strikes that affect public transportation;"

But then the statement could also mean the hassles involved on the front-end while Allure was still at sea for those two days are covered, such as the extra nights hotel, meals, but not the missed cruise days.
